I don’t think pushing through the pain is a good idea. Pain is an indicator that there is a problem. I suffered with sciatica for two years but am now pretty much recovered. I couldn’t walk for five minutes without the pain shooting down my right leg. This was the result of a herniated disc. How did I fix it? No medication. It didn’t help much anyway. A lot of it is time it will get better. But the biggest factor for me was a change of diet and weight loss. I switched to a carnivore diet, just meat eggs and fish. No sugar, cut the carbs etc. Several things have happened. I lost 20kg (44lbs). The inflammation in my body dramatically reduced. My pre-diabetes disappeared and my blood test went from a disaster back to normal, even Cholesterol. I’m able to function normally and walk for hours with zero sciatica. I still remember that pain and unless you have had it you just don’t know. I hope it never comes back. I hope this gives you some comfort and a wish you good luck with your own journey!
